SPECIFICATION formingpart of Letters Patent N o. 536,564, dated March 26, r189 5. Application filed May 25, 1894- Serial No. 512,465. (No model.)

To all whom 15mn/y concern,.-

Beit known that I, DAVID EDWARD Cannon, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented a new and useful Machine for Cutting Olf-` Corset and Dress Stay Steels, of which the following is a speciication.

My invention relates to improvements in machines for cutting off corset and dress stay steels or other metals of similar kinds for other purposes, in which are used a self feeding pair of rollershoperated in'conjunction with a reciprocating chisel, for cutting off the steel or other metal, and an endwise reciprocating table having an oscillating device for discharging the cut metal, operated by the downward mot-ion of the chisel. The endwise motion of the table is made by the incoming metal, and operates a lever and spiral spring, which in turn operates a tripping device, by which the machine is made automatic in its action. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l, is a top plan view of a machine constructed according to my invention. Fig. 2, is a side View of the same. Fig. 3, is a cross section of the endwise table. Fig. 4, is a view of the shift-ing lever angle arms and pitman forautomaticallyoperatingthe machine. Fig. 5, is a sectional View of part of Figs. l and 2, showing the key in the sleeve, and the fibrous friction collars, one on each side of the driving pulley. t

Similar letters and figures-refer to similar parts throughout the several views.

A, is the frame of the machine, having the shaft F and the pulley G located on it at one end, and a pitman connected to it at the other end. The lower end of thepitman is journaled on a pin attached to the crosshead. The cutting chisel is secured to the crosshead.

B is a table located horizontally crosswise, and in front of the frame A. On the under side of the table Bis the shaft Z, journaled in boxes. two jam nuts, two washers, the spiral spring, J, the sleeve 5, on which the loose pulley, H, is journaled, the driving pulley I, the cog wheel, U, and the under feeding wheel Y. The pressure of the spiral spring J, is through On the outer end of this shaft, are

the washer 5 exerted against the outer end of the sleeve, 5, which is held to the shaft, Z, by the key4 3. The sleeve presses up against the hub of the driving pulley I, and forcesthe opposite side of the hub up against the rigid collar on the shaft Z. The fibrous washers l, and 2, are placed between the sleeve 5 and the rigid collar on the shaft Z, as shown in Fig. 5. The driving pulley, not being fastened to the shaft Z, receives its driving power from the pressure of the spring J against the rigid collar on the shaft Z by friction of the washers and the hub of pulley I.

On the horizontal table B, are fastened two stands V. Securedv in these stands are the upper shaft, Z, which has the upper feed wheel Y, and the upper cog wheel U secured to it. In these stands V are boxes in which the shaft, Z, is journaled. On top of these boxes are spiral `springs X, and a washer. A thumbscrew is used for putting tension on the springs.

On the table B, are two guides D, D, having oblong holes in them through which they are bolted to the table B. Under these guides the thin steel WV, passes to the, chisel. Each one of these guides D, has upward projections through which pass the rods T, T. Each of these rods has a right andaleft hand thread cut on it by which the guides are adjusted to suit the different widths of steel.

The die E, is firmly securedto the table B.

This table has an offset in it, plainly shown at the left hand in Fig. 2. Located in this offset is fthe endwise reciprocating table C made in two pieces, and fastened together by bolts, as shown in Figs. 2 and 3. On the top of the table C are two uprights. In these uprights the rod, L, is journaled. On this rod are fastened the fingers S, S, and the spiral spring K, which is fastened at one end to the upright, and to the rod L at the other end. This rod has a set screw 4 inserted in it near the end next to the chisel. As the crosshead is making its descent it strikes the set screw 4 and suddenly turns the rod, L. The fingers, S, being behind the cutoff steel, or other metal, it is suddenly thrown out away from the machine. The lever M, is attached at one end to the endwise reciprocating table C; andy 'near the center it is fulcrumed on a stud, O. At the outer end it is connected to the angle lever N, which is connected to the pitman P, at one end, and the an gie lever Q is-con'nected to the pitman at the other end. This angle lever, Q, is journaled on a pin, a part of a bracket projecting out on the frame A. The purpose of these levers is to make the connection between the endwise reciprocating table, C, and the tripping device in connection with the driving shaft F.

The tripping device forms no featureof my invention.

Having now described my invention, the operation is as follows: As the steel W, is fed to the machine by the rollers Y, operated by the driving pulley I, and the cog wheels U, U, the steel passes along as indicated by the arrows until it strikes the stop, W', in the reciprocating table, C. It then moves thetable, C, as indicated by the arrows and dotted lines. The lever, M, fastened to the table, C, at one end is carried forward with it, this lever M, being fulcrurned on the stud, O. The spiral spring, R, attached to the lever M, and to the frame, A, draws the table, C, back again to its starting point. This same operation is continued automatically.

Having now described the operation of my invention, what I claim and desire to secure by Letters Patent, is

l. The combination in astay and dress steel cutoff machine, the frame B the shaft Z, located on said frame, on said shaft the spring J, the sleeve 5 the loose pulley H, journaled on said sleeve, the driving pulley I journaled on said shaft, the Washers l, and 2, substantially as shown and for the purpose described.

2. The combination in an automatic stay and dress steel cuto machine, of the table, B, and the endwise reciprocating table C, secured to the table B, the table, C, having a stop W', for the incoming steel W, the oscillating rod, L, journaled in uprights on the table C, said rod encircled by the spiral spring K, secured to said rod, the discharging.,r fingers S, S, secured to the rod, L, said rod having a set screw 4, by which said rod is oscllated, substantially as shown and for the purpose specified.

3. In a stay and dresssteel automatic cutoff machine, the combination of the endwise reciprocating table C, the lever M, secu red at one end to said table C, and fulcrumed on the stud, O, the spiral spring, R, attached to the lever, M, and to the frame, A,-snbstantially as shown and for the purpose described.
